In-tank EFI pump

Does anyone have a recommendation on either an in-tank EFI fuel pump that will not require tank mods, or an external tank pump that will meet EFI needs? I don't mind modifying the sender/pickup, but I really don't want to mod the tank.

I have a carter electric pump near the fuel tank now. Can I pump through that or will it lower my available fuel pressure?

I think I'm going to put the stock EFI back on the Magnum mill in my '72 Dart.

Thanks!

http://www.hotrodcitygarage.com/ make them to your order. Pretty reasonable.

A while back there was a thread about this. I believe he strapped the pump to the intank pickup and ran the power feed through the sealing flange. Check this thread.

The older Ford EFI had a low pressure and a high pressure pump. The EFI will need more pressure than the Carter can supply, so you will need to do something. For a daily driver EFI pump you will not need a ton of volume, so pretty much an inline EFI pump will work I would guess. Might want to look here. Keep in mind you will need a return of some sorts.....

you have to mod the tank but this is the best set up i've seen yet. uses an off the shelf GM pump. stock tank so you know it fits and tail pipes will fit properly (can't say that about some of the build to order tanks). the pump has a can looking thing around it that holds fuel around the pump when you turn corners. thats a must have when running EFI. EFI doesn't have a fuel reserve like float bowls on a carb. if your low on gas and turn a corner it will stall with out something there that will keep the pump pick up submerged.


you can buy an entire tank all ready to just bolt in. or you can use a tank you have alread and buy just the weld in part. be careful with a used tank though. injectors don't like all the dirt in a 40 year old tank..

not cheap but its a great set up and well worth it in my opinion.

Drove an old Ford Ranger that I put a EFI motor in it for years with an external inline pump and never had an issue with fuel starvation. Would imagine when the tank was low this could be a problem but never happened to me......

we use inline pumps on high hp muscle car builds as well as high hp turbo 4 cylinders one important thing is to mount it as close to the level of the bottom of the tank and run a good filter before the pump as well as after. then you only need to tap into the tank or filler tube for the return line.

almost forgot it does need to be efi pressure rated which is normally 45-55 lbs.

Many posts on this, so search. As mentioned, you can put the pump in the tank (see post), but probably easier if external, and certainly easier to replace, plus I always worry about the gas tank blowing up though that rarely happens (took out a Swiss Air flight).

Don't use the Carter pump in series, it may restrict the flow (did that). On 2 of my cars, I have an EFI pump in the engine bay. Works fine, despite what Holley, et al recommend. One is a Holley gear-rotor, the other is a Walbro, but formerly had a 90's Ford truck external pump. Get a sender that has a return tube. As many do, I use the $20 Corvette filter/reg that maintains 56 psi.
